Answer:
-4.3; inelastic
Explanation:
Initial price = $6.45
Initial quantity demanded = 600
New price = $6.95
New quantity demanded = 400
Percentage change in Quantity demanded:
= (Change in quantity demanded ÷ Initial quantity demanded) × 100
= [(400 - 600) ÷ 600] × 100
= (-200 ÷ 600) × 100
= 0.3333 × 100
= -33.33%
Percentage change in price:
= (Change in price ÷ Initial price) × 100
= [($6.95 - $6.45) ÷ $6.45] × 100
= ($0.5 ÷ $6.45) × 100
= 0.0775 × 100
= 7.75%
Therefore, the price elasticity of demand is as follows:
= Percentage change in quantity demanded ÷ Percentage change in price
= -33.33 ÷ 7.75
= -4.3
Hence, the price elasticity of demand is inelastic.
